Looking For Alaka

The big question of Looking for Alaska was, was it suicide or just a pure accident.   I think it was suicide.  all the evidence points towards it but anyway lets start at the beginning.  Miles was a semi loser from California when he decided that he wanted to go to the same boarding school as his father.  When he got there he found out that his roommate was a smoker.  Before hand Miles' father told him that he better not smoke or drink.  Turns out he does both.  About he moved in him and his roommate, "The Colonel", went over to Alaska's place, a friend of the colonel.  Miles or "Pudge" was instantly in love... ...until he found out she was with somebody else already.  Anyway after a long while of bonding and rising action the crew which included; Pudge, The Colonel, Alaska, Takumi another freind of The Colonel, and Lara, Pudges "girlfriend" wanted to play a prank of the ages. As Pudge and Takumi lured The Eagle, the Principal of the school, out of his house with fireworks, The colonel and Alaska changed the grades of some of their enemies.  Also Lara buts blue dye in one of those enemies, or weekend warriors who don't stay at school during the weekends, hair gel.  After the full success of the prank Alaska and the colonel had a drink off.  Once Alaska was drunk she dared Miles to hook up with her. After they kissed Alaska said that this was to much for tonight but this would "To Be Continued".  After they fell asleep like halfway through the night Alaska woke up to answer the phone.  After the phone call Alaska rushed into the room and demanded for the car keys.  Wanting to please the enraged Alaska they complied and gave her the keys.  The only bad thing was, next morning she was found dead.

Of course Pudge and The colonel blamed themselves for the death, but also wanted to investigate since at the seen of the accident their were no skid marks just a straight line straight into the police car that she crashed into. Also Pudge was in love with her. After a long and winded attempt to find out if it was suicide they realized that during that phone call she was drawing a flower.  Which reminded her of her mother.  Which also reminded her that this was the day that her mother died.  Here is where the controversy is.  Some people think that she killed herself because she was mad at herself for not going to her mothers grave on her death date, especially since she blamed herself for her mothers death, she didn't help her while she was having a seizure, but she was a little kid.  But also the place of the accident was on the way to the cemetery he mother is buried at, and Alaska was hammered.  So do you think it was an accident or was it suicide...
